Product Description

Rectangular silencer is a silencer frequently used in the ventilation pipeline system for its simple structure, low cost, good sound elimination effect and low pressure loss. As this silencer is relatively simple, one or more groups of silencer can be installed in the pipeline based on the dimension of ventilation pipeline to achieve the required effect in the practical application.

Structure features: rectangular tube silencer is supported by rectangular tube sound absorber which is composed of seal heads on both sides and sound absorption cylinder body in the middle. Sound absorption cylinder body is the sound absorption material wrapped with alkali-free glass fabric, and the surface cover is made of perforated plate.

It also has several production bases in other provinces to meet the production needs for continuous expansion. The company has complete production and detection equipment to ensure the normal and efficient production. Up to 2015, the company has provided over 800 noise control engineering consultations and designs, 500 noise control engineering constructions and 2000 sets of noise reduction equipment for customers in such fields as industry, transportation and building.

Laboratory

As the key environmental protection laboratory in Sichuan Province, our acoustical laboratory covers 521 square meters, and is composed of reverberation chamber, sound insulation chamber, silencer dynamic evaluation laboratory and impedance tube laboratory. The laboratory now is the largest noise control technology and acoustic material research & test center in southwestern China, and leads domestic noise control field. Silencer dynamic evaluation laboratory now is the largest silencer test platform in China. 

Our laboratory is designed by architectural acoustics design team from Tsinghua University based on relevant national standards and by reference to well-known acoustical laboratories at home and abroad. Main measurement instruments are manufactured by B&K, Denmark (a measurement instrument manufacturer ranking No.1 in the world, and providing noise and vibration solutions). The laboratory conforms to the testing conditions of CMA (China Metrology Accreditation), and has issued the reports conforming to CMA requirements for customers, and especially plays an irreplaceable role in the development of new productions and the detection of product quality. 

Our laboratory has established a resource sharing and advantage complement relationship with several institutions, e.g. Architectural Physics Laboratory of Tsinghua University andAcoustics Institute of National Institute of Measurement and Testing Technology, etc., and does business with them in product R&D, performance detection and other fields.  

The objectives of our laboratory are to correctly evaluate the sound absorption, sound insulation or sound elimination property of each kind of noise reduction product or structure with various measurement methods, support the design and optimization of noise reduction scheme, and ensure the noise of noise reduction engineering really meets the standard!
